Looked up an earlier post regarding turning cork/eva/hypalon. Frequent recommendation was to use 60/80 grit for major work and 150/220 for finishing. No problem finding sheets of 150/220 grit drywall "screens". I'm only finding 60/80 grit in drywall "sheets"...same thing or is there such a thing as 60/80 grit drywall "screens".

Only other thing was packets of "fine" or "medium" drywall screens, but no grit #s on the packets (at least as far as I could tell). Both appeared to have larger screens than the 220 grit screen I found.

Am I just looking in the wrong places (Home Depot, Lowes, OSH, Do-It Center...)?

Thanks!

A sheet can be cut into strips as wide as you need. Real hardware stores are more likey to have it than those you mentioned, but I don't think it really matters. I would think 60/80 get drywall screen would be considered "coarse." Most times, medium is 120 to 150 and fine is 220.

I bought a 'roll' of (60 or 80??) grit at NAPA that's working well for me.

Clarification...when I say "sheets", I mean like sheets of sandpaper as opposed to the large sheets of drywall screens. Both the drywall sheets and screens were the same size cuts.

The highest (coarsest) grit of the actual drywall screens was the 150. Anything else above that (80 grit) was a labeled a drywall "sheet" (and looked like a regular sheet of sandpaper). I'm trying to figure out if the 80 grit comes in an open "screen" like the 150 and 220.

Thanks.

TOny it does, but not sold at the Major HArdware stores like HD & Lowe's. YOu gotta look a little harder, find out where Construction/Contractor guys buy their stuff, then work out a deal to split up a gigantic 25 or 100 bulk pack of 80 grit.

IMHO - I cannot tell the difference in finish between 80, 120/150, & 220 screen - it all comes out smooth enough for me to finish off with regular 220, 320 Wet, 400 Wet & a piece of denim cloth (EVA/Hypalon)

Hi Billy:

Thanks for the confirmation and suggestions. That's what I kinda figured... Ran into the same kind of thing looking for the scotch brite pads (7446 and 7448). Found any and every other kind of pad, but those specific ones. Finally found both in an old paint supply store.

Anyway, it sounds like I can still get the job done with what I've found. I'm turning EVA for the first time and figured getting the coarser 60/80 grit would make the job easier and preferred the screens for this task. I'll give the 150/220 a go and see what happens.

Thanks to all that replied!

A Stanley Sure Form (sp) file is fantastic for quickly removing material. We're talking seconds!! You do have to be careful not to take to much off though! Works great for rounding of square EVA blocks.

You should also consider using 3M “Fre-Cut" sandpaper. It does not load like the cheap stuff. It also lasts a lot longer than ordinary sandpaper.
